Hi,

I've been hitting my head against a metephorical wall for the last hour trying to do something which seemed simple

Okay

I have a large circle and I want to put a smaller circle inside it so that the quadrant of each circle intersect at the o - Easy.

I now want to draw a line parrallel to the centre line of the larger circle but offset (in y direction) by x units - Easy.

Now for the tricky bit...

I want to rotate the smaller circle around so that it remains concentric with the larger circle (easy) and becomes parrallel with the offset line (so far impossible!)

What am I missing? I have tried everything I can think of: parallel onsap, geometric constraints, etc...

Thanks
